Will you get any convoy s2+ holsters…? They seem to fit the D4 well…

Do you have a fet driver that will run an xhp 70.2 in a convoy l2?

The 20mm should have some. The 17m FET driver is only 1.6mm, and it is an option for the 20mm FET+7135. 17mm, I am not planning on any, at least not for a while.

Efficiency, a difficult assessment as well as tough to maintain.

Richard trys so hard though! Like, I ordered 4 emitters that weren’t available bare, on 16mm Noctigons. I also ordered some quad boards. Richard saw a need and pulled the emitters from the Noctigons then re-flowed them to the quad board. Efficient! And then adjusted the price I paid, efficiency again!

Only problem with the efficiency is that I needed the 4 16mm Noctigons. lol I’ve got well over 100 of the 20mm SinkPAD’s, but somehow I can hardly ever find a 16mm MCPCB in my kit. Oh well, I’ll have to order some I guess, one day, if I can remember to.

I didn’t say this to gripe about anything, but if you, like me, actually want the boards your emitters are on for a different project it might be wise to clarify that in the notes so Richard knows. :wink:

Heck, if I’m not careful he’ll have my light half built for me before I can fire up my soldering iron! :wink:

Yo Richard…Love Ya Man! :smiley:

Sorry Dale! I had already reflowed them to see if they would handle direct drive, and assumed that you already probably had a million 16mms laying around.... DOH! I do appreciate your patience.

I got disappointing measurements of the XHP35 “E4-3C” I bought from your shop

XT12GT @5m with cheap Luxmeter

1. measurement
“E4-3C”
2210 Lux —> 55250Lux@1m

new LED reflowed

2. measurement
E2-3C from a BLF member that saw the real label
3610 Lux —> 90250@1m

E2 is the highest flux bin for the XHP35 HI

So you’re thinking Richard received some mislabeled or phony emitters from one of his suppliers?

The E4 3C I did have were from Cutter. From what I could tell, they were the real deal. I sold dozens of them to other BLF members, some of which I know tested them. I also know that V54 used a ton of them in his lights, which he tests in the light box and for throw. Now, we didn't have an E2 to compare against, but what you're measuring is more like C2. I don't do business anymore with Cutter.

At any rate, I find it interesting that you keep posting here about items you have for sale---and that makes me question your motives. I don't have any problem with you selling things, but there are better ways to go about it.

That’s pretty rude, for someone to sell/advertise their products in MTN Electronics’ topic…

I see no advertising text or link, as I posted none
I just pointed out that that LED I received from RMM that he got from cutter does have a way too low lux reading, it is possible they mixed up the good with some bad LEDs when they shipped him E4-3C

I could not test it before as I got my first luxmeter yesterday

No problem Dude, just tinkering anyway. I should have notated instead of assuming. lol

was about to order more XP-L HI v3 3c …I don’t see it on the website.

Are you going to be selling them again?

Unfortunately for now the V3 3C has been replaced with V2 3A. Sometimes getting the very highest bins is luck of the draw.

Ahh…

I’m sure the output difference’s minimal.

I tried to use the v3 3c on the tpad i got from you and move it over to the new quad board. But for some reason they won’t come off the tpad board. The LED got so hot I accidentally touch the corner of the emitter and top came right off. Super soft.

The TPAD quad takes even heat from the top and bottom to get a good reflow of the side pads because it uses a 2-layer copper construction for the electrical connections, so if only heated quickly from the bottom the thermal pad will reflow far before the side pads do, and it can be difficult to manage well with just a hot air gun or hot plate.

The silicone becomes extra soft when it is heated. I think that we've all accidentally done a hot dedome a time or two when reflowing emitters....

A few days ago I received a production model Emisar D1 for evaluation. It is a sweet little light!!! Quite the little pocket thrower. For those of you who aren't familiar with it, here is a quick summary:

  • Same battery tubes as Emisar D4 (good!)
  • Same user interface and driver as Emisar D4 (good!)
  • Same anodizing, style, and machining quality as the Emisar D4 (good!)
  • Larger ~ mm reflector. It is an excellent reflector for its size! Very tight and crisp hotspot.
    • Hotspot with an XP-L HI emitter is nearly equivalent to a C8 reflector with a domed emitter.
    • Spill is slightly larger than a C8.
  • Thermally it can run much longer than the D4 due to the single emitter and larger head.
  • I cannot think of a light that can directly compare with this at this price point.
  • Price will be the same as the D4 ($40).
  • I am not sure yet what all of the emitter options will be, but I think that the XP-L HI will be the one to get in this light.

picture not showing, maybe it’s my computer? I saw the picture however on the D4 thread! The wait begins…….

Got a pic of the D1?

Thanks! :slight_smile:

Very similar to the Godmes T01 but with a better cell for power supply (better UI too, of course). Interesting. And here I am with this 20700 bored tube not in use…. hmmmmm. Save me the first green one, gotta have it! :smiley:
